A study by the Cardiovascular Research Centre at the Royal Adelaide Hospital showed that even one can of Red Bull was enough to make the cardiovascular condition of university students similar to that of people with heart disease.

The caffeine content in a can is equal to that of a cup of coffee, certainly nothing to be concerned about. It’s the combination of the caffeine with taurine, an amino acid commonly found in energy drinks, that seems to be causing the adverse effects.

Although Red Bull is the product being picked on in the study, there’s no reason to absolve other energy drinks which use the same combination of caffeine and taurine. It’s probably a good idea to stay way from these energy drinks altogether.
